+ * X16 version adapted to work with both versions R38 and R39 of
+ Kernal and Emulator, and thus with prototype boards #1 and #2
+ * Some code cleanup around moving word headers to the heap
+ and related tmpheap cleanup
+ * load, thru, +load, +thru were removed from the v4th versions
+ like the x16 version that don't have block/buffer disk access.
+
+*3.9.2*
+
+ * X16: Zero page area used by v4th moved from $30-$5b to $50-$7b,
+ inclusive, so that it now doesn't collide with the ROM version of X16Edit
+ * Initial prepartion for and implementation of tmpheap
+ * Some minor cleanups and bug fixes.
+
+*3.91*
+
+ * X16: Initial version
+
+*3.90*
+
+ * Built-in INCLUDE stream file interface
+ * Separate versions with and without BLOCK words
+ * C16-32k version resurrected and fixed
+ * An adapted subset of the ANS test suite is made to pass
+ * Makefile setup for build and test
+ * Build sources moved from BLOCK disk images to stream sources

Philip Zembrod	3a4eff97c4	Reduce the direct use of the Kernal variable IOStatus by using the Kernal API routine READST. Also remove the code referencing the old R38 RAM/ROM bank switching registers. Finally remove some unused Kernal variable labels.	2022-08-07 22:42:40 +02:00
Philip Zembrod	2c86e4809f	Remove references to the Kernal variables InDev and OutDev which are needed to implement BUSOFF via CLRCHN and which moved on X16 between r38 and r41 and will likely change again, and replace with own variables and calls to UNLSN and UNTLK.	2022-07-31 23:54:37 +02:00
Philip Zembrod	cae5f7c94d	Get v4th-x16 to work with r41 of x16emu and x16 ROM. Main change is that c64key? and getkey are implemented through new Kernal API calls instead of direct reading the keyboard buffer. A separate intermediate test target for r41 is introduced. But also the main x16 target is switched to r41 now. Also, the KEEPEMU env var is introduced to run-in-x16emu.sh for debugging that has proved its usefulness in cc64 emulator scripts.	2022-07-31 21:56:33 +02:00
